Where Did You Put Your ARB CKMTA12 (Air Compressor)?

Taking some inspiration from Alia's tank mount, I measured things and concluded both the ARB compressor and 4 liter tank will mount between the frame rails underneath the winch. Plenty of room there, length of wiring and plumbing runs are minimal and accesible. It is a little exposed, but no worse than many under tray mounts I've seen on trucks in Australia. A Harbor Freight winch mount plate will supply the basic mount. Should be able to do most of the assembly on the bench then lift into place for the final hookups.
 
I've got the discontinued OVS version of this same compressor .. but the mounting is the same. Started witih the Torfab bracket for the firewall but when I switched to dual batteries I had to remove it, as the compressor would bump into the newly relocated washer bottle. If anyone here can use this bracket, hit me up we can ship it to you. no really, you can have it.

I moved the compressor to the side of my ARB drawers. Drilled some holes in the trim kit panel and extended the switch wires, and a quick disconnet fitting for the air hose. So to use the compressor just hit the switch and plug in a hose.

Under the cover you can see the compressor just barely fits in there... it's a combination of resting up against the wheel well, and a few screws going in to the drawer.

The power is fed from a fuse panel on the other side of the drawers... 4ga + and - running from the 2nd battery. I'm not concerned with heat- it's usually cooler inside the truck than it is inside the engine. And I figure I can just pop off the cover plate of the drawers when I'm airing up. Only downside is any passenger not helping with airing up gets to listen to the air compressor and full volume.
 
It's really not that loud though. My wife hasn't complained and it's right under her seat.
 
One concern with the under winch mounting I am contemplatng, really any external mounting, is keeping excess crud out of the filters. Does anyone use a particular plastic snap lid that fits over the filters snugly (and which would be removed when using the compressor)?

Alternatively, I recall some reference to using a different air filter in place of the ARB-supplied ones. Anyone know what these might be?
 
I haven't tried but is it possible to remote mount, similar to how breathers for diffs are mounted?

People mount them behind the fender wells of jeeps. I think the biggest issue you will have is accidently running it during a water crossing for a locker engagement. And extra cost of occasional replacement of filters. It's not the best location but you'll probably be fine.

Both of mine are plumbed with nylon tubing and the filters remote mounted behind the primary battery

You can get a glympse of them in this video

Hmmm, that's an interesting location nakman. In my drawer system the fridge sits next to that location, so I use it to store items that I don't need often AS THE FRIDGE LIMITS ACCESSIBILTY! The air compressor would fall into that category, plus it's within the supplied wiring harnes length's a a 4 gauge cable going up front. After looking things over, keeping the compressor inside is probably for the best. My cubbyhole there already has a vent above it, because it used to house an inverter. The air tank will need to go between the LRA auxliary. tank and the inside of the rear bumoper, but there's room to add a second aur tank
 
I ended up putting my dual compresor ARB in the space to the left of my fridge drawer. Some of the piping/wiring passes through the lower left fender area but mostlyit takes up the last 2' of a 6" wide space that is about 9" tall.There is a vent about 3" wide by 10" long that allows for substantial vertically flowing ventilation. I've got to get back in there to adjust some unrelated wiring soon and will taker pics then. The switch is on the drawer sideinsiden the driver's side rear passenger door. The ARB air tank resides in between the back of the bumper and the aux;iliary fuel tank. I have a nipple to hook up the hodes to centered about my rear hitch receiver.

Getting ready to install an ARB CKMTA12 air compressor system along with the ARB 4 liter air tank. I have the ARB bracket kit to facilitate the project. Has anyone managed to make this fit into an ARB bumper, which would seem to offer some advantages in terms of keeping it out of the way and limiting how far power needs to be routed to it? Other potential locations are more remote, such as the right rear fender or somewhere along the frame. Thought this would be a good place to collect examples of installs to assist others with their installs, along with the pros and cons of each.

Right rear quarter panel is an ideal location IMO with the tank under the rig.
 
why the tank? Unless you're running an air locker, or train horn, or '64 Impala suspension... the tank is just getting in the way of filling tires. sure it'll feel like the first half of the first tire is a little quicker to fill, but then it ultimately takes longer as you have to first pressurize the tank before you can add air to any of the other tires, it's like you're airing up 5 tires instead of 4. I've run this both ways, in a couple different rigs. Filling right off the compressor is faster/simpler than adding a tank.

Promised pics to follow...

I've got one of those All-tops inflate 4 at once rigs and figured the tank would help with that, Plus did want the option to run air tools. And it's only a 4 liter tank, so the system pressurizes in a jiffy.

Looking down, on the left is the open space with the fridge slid out. The vent was left from when I housed an inverter in that space.

IMG_0946 Medium.webp

Turning 180 degrees, with the lid open, there's just enough space to mount the compressor assembly. I used lag bolts into the wood drawer frame to attach the bracket holding the compressors.

IMG_0954 Medium.webp

View from the tailgate looking forward. I have roughly 9" of clearance under the drawer deck, just enough to squeeze everything in.

IMG_0958 Medium.webp

Turning 180 again and with the compartment lid open, you can see how the small notch I made in it leads the air output line into the fender space. It dives down, turns and comes out through a grommeted hole towards the air tank.

The air tank sits on a bracket attached to the rear bumper.

The line from the tank leads to the ARB nipple situated just above the hitch receiver.

Looks great! Nice work
 
I have mine in the empty area behind the rear passenger tire inside the cargo area. It uses otherwise wasted space, and is convenient, but is loud.

I agree and that’s how mines setup tankless
And IMO it’s fast.
But I run Beadlocks so not much chance of popping a bead. And that’s where a tank shines resetting a bead 😉

$227 is definitely steep. Looks like its on sale for 193, but I just pulled up my receipt and I paid $171US + shipping for $187 total.

If you have access to sheet metal and the ability to bend you can probably easily make something similar. Its probably way more robust than it needs to be.
